Wikipedia agrees with you about who is circumcised:
The World Health Organization (WHO) has estimated that globally one-third of males aged 15 years and over are circumcised, with almost 70% of those being Muslims.
Prevalence of circumcision - Wikipedia, the free encyclopedia
So, unless one is a Muslim or Jew, it's not a big deal to be natural.

I have read that at one point in America that 90% of males had been circumcised, this was from turn of 20th Century until about the mid-1960s, this now has diminished significantly. Canada though didn't mimic her American neighbours, Canada never had a high rate of circumcision, I don't know if this is because they followed the lines of their Commonwealth kin.

I've often wondered why there's been such a high circumcision rate (70-80%) in USA, whereas most immigrants came from countries with low rates.
I've concluded one main factor is
MONEY ... for the medical profession (& Dental which loves X-rays).
In USA, money is king. Follow the money to understand decisions by the rich & powerful.
Circumcision procedure = income.
USA doctors also advise their patients to use
anesthesia, even when not necessary.
In my own case, i had a colonoscopy
without anesthesia, although anesthesia is standard procedure in USA but
not in other countries.
I also had my wisdom teeth pulled while conscious, against the doc's advise. The alternative, NO2 (laughing gas), was a lot of fun & the procedure only took 12 minutes!
I'm sure my doctor's colleagues were not happy that i reduced their income.
